Be it known that l, Gns'rar H. Anemone, citizen of the United States, residing at Bray, in the county of Pennington and ,State of Minnesota, have invented a new and useful Heating and Ventilati g System for Buildings, of which the tollo ing is a specification.

This invention relates toheating and ventilating systems and ventilators to-r resi dences, hotels schools and other buildings which are heated from a turnace laced in the basement or lowest story ot the uilding.

The object out the invention is, to provide such buildings with a fuel saving heating system in which fresh air is circulated from the top of the building down to the furnace and after being there heated it is distributed through tubes to the various rooms of the buildingand circulated as loud air by other tubes from said rooms up through the top of the house, and to so arrange the fresh air tube, that it is in contact with the smoke stack out the furnace and the tool air outlet tubes, so as to absorb some heat from them before reaching the heating chamber at the furnace, where it will then require less fuel to raise the temperature of the air to the standard required for the rooms. I

in the accompanying drawings: Figure 1 is a vertical section oil a building equipped with my new heating and ventilating sysh is an enlarged diarnetrical vertical section at the ventilator or part of the system arranged in and above the root of the building. 1 lg, 3 is a sectionon the line M in Fig 91,. Fig. 4c is a section on the line h-b in Fig. 2.

Referring to the drawings by reference numerals, l designates the basement, 2 the first story, 3 the second story, 4:: the attic, 5 the root, 6 the walls and 7 the partitions and :8 the toundation ota school house, or other building, having in ts basement a furnace 9,.whose doors IlOare exposed through the trout wall of an air heating chamber ll,

which is spaced about the furnace and ire-i.

ceivcs ,cold or fresh air down through a lib large'upright tube 12, while centrally up through said 'tubel2 the smoke stack 13 crliron furnace to the required distance above the roof where its top is pro videdwith a hood 14, which has a sleeve 15, ,retalned by a, nut 16, upon a post 17 on which it is rotated by the action of the wind on a vane l8, seas to hold the hood M- as a Specification of Letters Patent.

wind shield over the side of the top of the smoke-sthck l3 and the foul, air pipe 19, or l9 that are subjected to the force of the wind. Said post 17 is mounted in diametrically arranged bars 20 fixed in said tubes 13 and 19 (see Fig. 4)..

Said foul air tube 19 is concentrically arranged about the cold air tube 12 and the latter likewise about the smoke-stack 13.

Above the root 5 the foul air tube is formed top portion 19 ot the foul air tube. From registers 21 near the floor in each room the foul air passes upward from the air heating chamber 11,-through tubes 23 and registers 24: in the upper part of each room.

To increase said air circulation by a forced downward draft in the fresh air tube, the upper part oi? the latter is pro vided with a cylindrical wind chamber 25 rotatable on rollers 26 and having in one side a large opening 27 (see Fig. l) for the wind to blow into, and lateral wings 528 for the wind to act on and hold the opening against the wind. The lower end oi the cylinder is guided by rollers 29 mounted upon a cylindrical base 30 lined on the root, and the upper end ot' the cylinder is protected from snow by a circular shield tl l'iued on the reduced portion it of the tool air tube,

' of a smoke stack therefrom up through the building and its root, a trash air tube spaced about the srnolre stacli'. and'eutending to a point between the root and the top of the smolrestach, a foul "air tubespaced about the trash air tube and having its upper-part reduced in diameter above the top at the fresh air tube, and below said reduction formed into outwardly arched tubular branches between which the fresh, air is to pass into the top of the trash air tube.

2. in a house heating and ventilating system, the combination with a fire apparatus, of a sinolrestaclr therefrom up through the building and its root, a fresh air tube spaced about the srnokostaclr and extending to a till llllll fresh air tube and below point between the roof and, the top of the smoke-stack, a feel air tube spaced about the fresh air tube and having its upper part reduced. in diameter above the top of the said reduction formed inte outwardly arched tubular branches between which the fresh air to pass into the top of the fresh air tube 5 a refiery hoeai mounted on the top if the smoke stack and the foul air tube and means for the Wind in acts on and turn said hood with its eiosed side to the Wind, and a rotary eeeeee wind chamber about the part of the foul air tube having spaces for the Wind to enter the fresh air tube, said wind chamber having a. front opening for the wind to enter and means for the Wind to act on and held the chamber with the opening against the Wind, said. means consisting of two Iatei'el rezir- Herd efiiverging vanes one fixed each side of the Wind chamhe In testimony whereof I efiix my sigma-- tare.
